St. Augustine Grass didn't fully return and what did is yellow
I live in the DFW area of TX. Last summer we had thick, green St. Augustine in our front yard. This year some has returned but bermuda has mainly filled the yard. Not many weeds, just not a lot of St. Augustine. What is there is yellow in places. I try to water and fertilize and mow at a high setting.
There does seem to be a thick layer of last year's grass (brown) and we had a abnormally long, cold winter.
I am new to St. Augustine grass. Was there something I should have done with the thatch last year to bring back the green, thick grass this year?
